Guest AlmightyJu Posted February 11, 2013 Share Posted February 11, 2013 Hi guys, I'm trying to find the tacho wire coming from the igniter (its a N/A 93) since I want to get the rpm signal for a circuit I'm making. I think i found it but not sure, the pics are taken from the passenger side down by the ECU and theres a black and white wire and it looks to be in pin 29 which is right according to the manual I have, but the voltage doesn't seem to change when i rev. with my multimeter (i dont have an oscili :/) on the ac setting it reads about 23 to 26v and on dv its almost a steady 9. I was expecting it to range from 0 to 200V or 12V or maybe even 5V, but it doesn't seem to budge Am I missing something or have I got the wrong wire? I'm at a loss :/ thanks!
